3Delight is a very fast RenderMan-compliant renderer designed to produce photorealistic images for serious production environments. Some of its features include ray tracing, global illumination, motion blur, depth of field, subdivision surfaces, programmable shaders, quality antialiasing, and antialiased multi-depth shadow maps. The API and the shading language are very similar to what is described in the RenderMan interface documentation.

3dom stands for 3-Dimensional Object Modeler. The aim of 3dom is to offer a tool to model reality with user-chosen accuracy, and user-chosen inclination for a particular purpose, which can be gradually improved and extended. 3dom is designed to be a general-purpose modeler, however it is especially inclined to model scenes for Global Illumination purposes.

AC3D is a well established, fully featured 3D modeling package. It features an easy to use interface, powerful polygon and vertex editing, a UV mapper, 2D/3D text, and subdivision surfaces. It supports many 3D file formats.

Ghostscript is a processor for PostScript and PDF files. It can rasterize these files to a wide variety of printers, devices for screen preview, and image file formats. Since applications tend to prepare pages for printing in a high-level format such as PostScript, most Unix users with low-level bitmap printers, such as inkjets, use GhostScript as part of the printing process. In addition, Ghostscript is capable of converting PostScript files, functionality comparable to Adobe Acrobat Distiller, but on the command line. In addition, Ghostscript is used for file import and viewing by a great many other applications, including xv, ImageMagick, gimp, and xdvi. Several GUI wrappers for viewing PostScript and PDF files exist, including GSview, ghostview, gv, ggv, and kghostview. This is far from a comprehensive list.

album is a free HTML/XHTML photo album and gallery

Allegro is a multi-platform game library for C/C++ developers that provides many functions for graphics, sounds, player input (keyboard, mouse, and joystick), and timers. It also provides fixed and floating point mathematical functions, 3D functions, file management functions, compressed datafile, and a GUI.

AniTMT is a software package which is used to create photorealistic films with your PC. It has a new script language to do this. As the raytracing process takes much time, it can be distributed in networks.
